Notice of Availability; Alternatives for New Source Review

Applicability for Major Modifications Solicitation of Comment

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability; extension of comment period.

-----------------------------------------------------------------------

SUMMARY: The EPA is hereby extending by 45 days, the closing date of

the public comment period regarding EPA's notice of availability

published July 24, 1998 at 63 FR 39857. The original comment period was

to close on August 24, 1998. The new closing date will be October 8,

1998. The EPA is soliciting comments on a specific alternative for

determining the applicability of new source review (NSR) to

modifications of major stationary sources under the prevention of

significant deterioration and the nonattainment provisions of the Clean

Air Act. This alternative would allow any source to legally avoid major

NSR for a physical or operational change to an existing emissions unit

by taking an enforceable temporary limit on an emissions unit from that

unit for a period of at least 10 years after the change. In addition,

the Agency is seeking comment upon when and under what circumstances

permitting authorities should have to review the emissions level set

under a plantwide applicability limitation (PAL) for any source.

Industry groups have asked for an extension due to the complex issues

addressed by the notice of availability. All comments received by EPA

on or prior to October 8, 1998 will be considered in the development of

final regulations.
